As a detective, I analyze clues and gather evidence to solve mysteries. When I saw the crossword clue ‘Words on the street‘, I immediately thought of informal language. The word ‘street‘ can refer to an urban area or to the world of youth culture, both of which are associated with slang. Slang is a type of language that is typically used in casual situations and among specific groups of people, like teens or subcultures. It is often used to express a hidden meaning or to convey a sense of identity or belonging. With this in mind, I confidently concluded that the answer to this clue must be the word ‘SLANG‘. My insights and thought process in this case helped me unlock the mystery and move one step closer to solving the bigger puzzle.
